After you file

I have this problem as well.  TT desktop says I get a Fed refund of ~1,300.  I just received a letter from IRS saying I owe ~500 plus interest.  The letter says, "We changed the amount claimed as Recovery Rebate Credit on your tax return..."

 

They supplied 5 possible reasons. The only one that applies is, "The amount was computed incorrectly.  Why would TT compute the wrong number when my software is up to date?  I'm concerned I can't trust TT any longer.

 

Who do I believe, the IRS or TT?  Please help me understand how to best deal with the IRS.  Should I pay, or trust TT and fight the IRS?
