1042-S form (income code 16) - Unable to e-file

Hello,

I am a resident alien and received a 1042-S (income code 16).

I reported it as a fellowship, and reported the income tax withheld as "Other income taxes paid in 2020". However, I am not able to e-file (I am receiving a message saying that my income tax withholding is greater than my income.

Is this correct? Is there a way to report the fellowship under income so I can e-file?

Thank you!
