This happened to me too--with THREE 1099-INTs. In two cases, Turbo Tax incorrectly loaded the two-digit state and that didn't align with the ZIP code, it rejected it when I went to electronically file. In the third issue I had, Turbo Tax was looking for some supposedly missing CUSIP number on a 1099-INT that wasn't there to begin with.
The easiest way for me to correct this was to back to the Income section, delete the original record for the 1099-INT, and THEN manually re-enter the 1099-INT information (which for me consisted of only the name of the financial institution and the amount of interest in box 1--it doesn't ask you to input the bank or taxpayer addresses when manually entering).
It's probably best to delete the erroneous original FIRST, because if you instead first manually re-enter the information (so at that moment both records are there), it is hard to tell which is the "wrong" one to delete, and which is the "right" one that you manually just-re-entered, because the only information that displays on BOTH records is the name of the financial institution and the dollar amount. In one of my three glitches, I inadvertently deleted the "right" 1099-INT that I had just manually entered (instead of the wrong one), and so the same error popped up when I went to electronically file.
