Unable to file Error: You've entered tax deducted on a slip but have not reported any income.

I was unemployed in 2023. I collected IE during the year, and entered the info from my T4E slip. I don't have any T4 slips, obviously. When I went to netfile my return I get an error with a suggestion to fix: You've entered tax deducted on a slip but have not reported any income. If this is because you were self-employed, more information is required.

 

I don't know how to fix this error. Help please.
