After you file

Not all corrected returns have been processed yet ... the IRS said it may take the rest of the summer to process all of them and you are not alone as the IRS still has millions to go.

 

And if you got an email from TT it did not tell you to amend immediately but only that you "MAY" need to amend if the change made you eligible for something like a credit  not already on the return.  Of course rule #1 of amending returns is that you NEVER amend a return until the original return has finished processing and you have the original refund in hand.  That is the first thing the program asks you  as you start the amendment process and if you say you did not get the original refund yet it stops you and tells you to wait.
