I received a 1099-MISC from a client and didn't realize until I went to file that they forgot to add a state to box 17. Box 17 had their TIN and box 18 had an amount, but no state in 17.
I asked them for a corrected form, and they sent one, but when they corrected it, the account number was changed. From what I can find online, the account numbers have to match between corrected forms or else the IRS/State won't know they're the same transaction.
If they submitted this corrected form without making sure the account numbers match, how do I know there aren't two forms on file now, and that I won't get an audit flag for seemingly skipping one on my return?
