Hello,
I'm happy to hear you're using QuickBooks Self-Employed to manage your business and personal finances. The Self-Employed product is great for solo-entrepreneurs who want to make the most of their bookkeeping experience. I'd be happy to explain how the bank feed works in regards to linking multiple accounts from the same financial institution.
It's certainly not uncommon for someone to have both business as well as personal bank accounts with the same financial institution. I know how important it is to have all of your bank accounts linked with your QBSE account. You're able to add as many different accounts from the same bank as you'd like. If both accounts use the same username and password, you'll have the option to select which account you'd like to link.
I hope this helps you get back to business. Here's more information about using the bank feeds in QuickBooks Self-Employed: Connect bank and credit card accounts to QuickBooks Self-Employed.
If you have any other questions about this, or if you need a hand connecting your accounts, I'd recommend reaching out to the QuickBooks Self-Employed team directly here: Contact QuickBooks Self-Employed.
Cheers.
