Several days ago, on January 30, 2023, I e-filed a 2021 tax return and received this rejection error:

Error message: Form 1040, 'WithholdingTaxAmt' must be equal to the sum of the following: [(1) all 'WithholdingAmt' in [OtherWithholdingStatement] and (2) all Forms W-2, 'WithholdingAmt' and (3) all Forms W-2G, 'FederalIncomeTaxWithheldAmt' and (4) Form 8959, 'AddlMedcrRRTTaxWithholdingAmt' and (5) 'TotalAmt' in [BackupWhSchedulesK1Statement] and (6) all Forms RRB 1042-S, 'FederalIncomeTaxWithheldAmt' and (7) all Forms SSA 1042-S, ('NetTaxWithheldAmt' if it has a non-zero value, otherwise 'FederalIncomeTaxWithheldAmt')] unless Form 8958 is present in the return. When evaluating this, a tolerance of $5.00 is allowed.
Solution: This electronic filing reject is the result of a change needed for updated IRS requirements. This reject will be addressed in the latest release. Please update the program and re-transmit the return.
Code: F1040-034-07

I checked all the withholding amounts in the tax return against the client's wage and income transcripts. Everything matches. Any ideas how to solve this error?

Thanks
