Hello @TMGgmt,

Manually uploading your transactions with the unsupported versions of QuickBooks is unavailable. You'll want to update your software to the supported versions at least.

Here's an article you can read to learn more about unsupported versions and service discontinuation: QuickBooks Desktop service discontinuation policy and upgrade information.

You can always visit our Help Articles page in case you need some ideas and references in managing your account and transactions.

If there's anything else that I can help you with, please let me know in the comments. Always around ready to help.
