I have a suggestion that might help if you did not get this resolved. One of my banks does not export their .qbo file with the right information in it for QB to read it properly. It is missing two lines of code that include the QB FID number so I have to add it manually to the .qbo before I import it.

IF this is the same problem you're having (it might be something else), first, find your bank's "FID" number in QB's FID directory. (Check this article for more info: https://quickbooks.intuit.com/learn-support/en-us/bank-feeds/update-the-financial-institutions-direc...). You can go here (https://ofx-prod-filist.intuit.com/qb3100/data/fidir.txt) and use ctrl-f to search for your bank name and see if you can track it down.

Then, open the .qbo file using Notepad (I right-click on the file name in File Explorer and choose "open with Notepad"). Find the line that starts with <DTACCTUP>. Immediately after that line, insert the following lines of code:

<FI>
<ORG>BANK NAME (as shown on the FID list that you searched)
<FID>XXXXX (the FID number for your bank from the FID list)
</FI>
<INTU.BID>XXXXX (the FID number again)

Then save the file. You should now be able to import it as you usually do and QB will recognize it as a valid file.
