Someone told me in a Reddit thread that Free File Fillable Forms, although it doesn't allow alphabetical values in the SSN field (last time I checked, anyway, which was last year), permitted him to successfully e-file while leaving the NRA spouse SSN field blank (return accepted by the IRS). So I'm going to give Fillable Forms a try this year, as my return is uncomplicated (identical to 2020 except for the numbers) and I don't feel like forking over any dough . Good luck.
