Hey Bob,

Thanks for the reply.  Not sure I understand the question so I'll tell you what I know.  The return was e-filed with an amount due to the IRS of $8,566.  This was shown on the return and was paid on or before the May 17th deadline.  The IRS notice confirmed this payment.  All good. 

The amount adjusted by the IRS notice is $1,591.97 which I believe was adjusted for a  disallowed Recovery rebate credit plus or minus interest and other credits as follows:

Rebate Tax Credit (1040 line 30)      $1,936.00

Less other Credits (IRS calculated)   $   355.02

Interest (IRS Calculated)                     $     10.99

Amount due to IRS                              $1,591.97

What I don't understand is why the Rebate Tax Credit was disallowed?

I appreciate your looking at his and hope this helps.
