In the IRS app they state they used my 4090$ refund to pay back taxes.Turbo Tax refund states it was 5190$....Any help?

If the IRS changes your refund amount then they also send a letter of explanation in a few weeks.

The difference is $1,100.  That could be the first and second Stimulus for a dependent.  Did you have 1100 or an amount on 1040 line 30 for the Recovery Rebate Credit?  Did you get the full amount for the 1st and 2nd Stimulus checks?   There were 2 boxes to enter the amounts you actually got (including for your dependents).  You had to report the right amount in each box. If you put the total in 1 box it would give you the other amount again. The IRS knows they already sent it to you. Line 30 is only if you qualify more.
