MD PTE Tax paid for nonresident in 2020

[dsocpa]

I have a fiscal year S corp. I'm trying to file their FY 2020-2021 MD 511 tax return.  The company's total federal income is less than the MD income because the add back of the PTE tax.  They paid a couple hundred more than what ended up as due so the 511 shows an op on line 18 to apply to next year's estimated tax.  All seems good until I try to clear the efile diagnostics errors.

I've tried everything but the error keeps coming back that there is a difference between total income on reported on form 511 (total distributive pro rata share of income) and Schedule B.  The difference is the total income MD income.  Schedule B shows 2 50-50 shareholders with the total share of income totaling the correct amount.  

Note this error does not show up if I just do an error check.  Only the Review with efile diagnostics.
