After you file

Depends......was box 2a of the original 1099-R, lower than box 1 by the corrected box 5 amount? 

...or was it lower by the original box 5 amount?

 

IF the Original 1099-R you entered, already had box 2a lower than box 1 by the corrected amount, then you likely don't have to do anything...other than keep those forms in case the IRS has a question later.

 

IF box 2a was reported properly on the original 1099-R, you should also check your 1040 line 5b vs line 5a to make sure only the 2a  value went into 5b (if you had other retirement distributions...those also add into lines 5a & 5b so you may have some math to do)
