I was forced to upgrade from 2015 to 2019 because Intuit stopped letting me import bank records in my version.
After the upgrade for one bank account, the account number, routing number, and bank feed customer id are all corrupted as strings. I cannot fix the account numbers until I deactivate online services. But deactivating online services crashes QuickBooks.
I've manually exported my accounts to an IIF file, editing the account details, but it won't import.
What else can I do?
Hello there, @mpeterson.
Welcome to the Community. I'm here to lend a hand with importing your bank transactions in QuickBooks Desktop.
Let's start with updating your QuickBooks to the latest release to refresh its connection and help you import your transactions smoothly. Once done, let's proceed with importing your IIF file in QuikBooks Desktop.
For detailed information when importing IIF files, please refer to this article: Improved IIF Import in QuickBooks 2019
However, if you still encounter the crashing issue of your QuickBooks, you can check out this article for more troubleshooting steps:

Not sure if you're a bot but...
Yeah I had already updated QuickBooks to the latest release before this.
Like I said, I already tried importing the IIF file. Here's the errors though:
For the bank account I get this error:
[ERROR] The record at (or starting at) this line could not be imported. There was an error when modifying a Accounts list, element "Redacted Bank". QuickBooks error message: Unknown Error 
For that bank account's online info:
[ERROR] It's a list or transaction that is not supported by the IIF import process.
Let me join in this thread, mpeterson.
There is a reported issue about IIF files not importing into QuickBooks 2019. Our engineers are already investigating it and they're working diligently to get a fix as soon as possible.
I suggest giving our QuickBooks Technical Support a call so they can add you to the list of affected users. Here's how:
Rest assured, our team is doing their best to get a resolution for you. If you have other concerns, you can always visit us anytime.
Ended up having to call tech support twice. They eventually had to manually fix my company file. Works fine now. Spent $1000 of my time getting this to work. Let me know who I can send my invoice to.
Hi there, @mpeterson.

If you want to send us the invoice for your subscription, I need to pull up your account and be able to locate where the charge is being placed. Since my access to the accounts is limited in this public forum, I recommend you to get in touch with our Phone Support.

That should do it.
