Why are there critical diagnostics on my divorced taxpayers tax return requesting 'domestic partner' information for income allocation sheet saying it a MFS return cannot be filed without that information when the return is marked as single taxpayer and not MFS?   The taxpayer has been divorced for the second year in a row and the return is marked single for 2018 and 2019.  The 2018 return e-filed just fine with no errors especially this one but now for 2019 this is the error.  Why?
