Schedule 1, line 1 doesn't match Q&A

State refunds recd in 2023 in the Q&A don't match the number on Schedule 1 line 1.   The amount reported on Sh1, ln 1 is lower.  This could result in underpayment.     

 

TT says Sh1, Ln1 "this is a calculated field", but doesn't show me a worksheet with the calculations.    Is there a way to see the calculations behind the entry on the IRS Form?
