Problem using 'Assign an Account' after adding a new bank account

Hello there, @lotus43. I want to ensure this will be taken care of. 

To clarify, are you trying to enter a transaction which requires to select an account? Or is the problem happening on the Bank feeds page? That information is a great help so I can provide a timely and accurate solution.

You can also attach a screenshot for that specific part of QuickBooks Desktop so I can review it further. If you receive any error or warning messages, you can also include them in your response.

I'll be waiting on your response. Thanks for dropping by. Stay safe and have a good one. 

I have appended a PDF showing stepwise screenshots (with some additional lines of notes) that should outline the problem.  The CANNOT ENTER in the line has simply been added to let me know that I cannot enter what I want.

Hi there, lotus43. 

I'll make sure you'll be able to assign an account in QuickBooks Desktop (QBDT). 

Normally, you can use the Quick Add button to automatically add a name that isn't on the list. If you already choose an account on the 2nd line and the issue persists, we can run verify and rebuild data utility. A part of your QuickBooks data may have been damaged. This causes the program not to assign an account. Beforehand, make sure QuickBooks is up-to-date.

Follow the steps below on how to verify data:

1. Go to the File menu.
2. Choose Utilities from the drop-down option.
3. Select Verify Data.
4. Click Ok to continue.

Next, here's how to rebuild data:

1. Go to the File tab at the top.
2. Select Utilities from the drop-down option.
3. Choose Rebuild Data.
4. Click Ok on Rebuild has completed.
