I have 2020 QuickBooks desktop for Mac, what are my options?

I have a 2020 version of QuickBooks desktop for Mac. I assume soon this will stop allowing me to use online banking and then it won’t be supported. I have 10 years worth of company data and the most important part is I have 10 years worth of PDF receipts and invoices attached to each transaction. My understanding is that I can’t switch to QuickBooks online because it won’t import my attachment library and connect all of those attachments to the transactions.

I only use QuickBooks on a very basic level. I would like to continue using the desktop version on my Mac. But I’m not seeing any reasonable solution for that.
