SC-F1040-015 e-file error
If Schedule C (Form 1040), 'TotalAreaOfHomeCnt' and 'HomeBusinessUseSquareFeetCnt' both have a non-zero value, then 'HomeBusinessExpenseAmt' must not be greater than (1500 plus the sum of all Form 8829, 'AllowableHomeBusExpnssSchCAmt').
The IRS doesn't allow reporting both methods of home office expenses in the same return.
Solution
Due to IRS e-File specifications, the return will need to filed on paper with Form 8948.
