Thank you. We’ve been using the vouchers. They just took this first payment automatically out of the refund. Can we use that number to change the amount of the estimated payments? 


 I don't think you are set up for automatic payments from the IRS.  Here are some things it could be.

 

#1  Did you select to apply part of your refund to the 1st estimated payment?  Check 1040 line 36.

#2  The IRS kept part of your refund for something you owed.

#3  Were you having any fees deducted from your refund? 

#4  Could it be for the state refund?   At the end Turbo Tax gives you the combined net amount of federal and state.
