IND-366 e-file error
If 'NRALiteralCd' in the return has the value "NRA" and the filing status of the return is married filing separately, then 'ExemptSpouseNm' must not have a value.
Solution
If the filing status is
Married filing separate
and you've marked the Claiming spouse
and Nonresident alien spouse without ITIN
checkboxes on the 1040
screen, in the General
folder, then you'll need to paper file the return.
