How much earned income did you have? From W2 box 1 and self employment Schedule C Net Profit? Do you have enough Net Profit? You can only contribute up to your net profit reduced by the deduction allowed for one-half of your self-employment taxes. See IRS publication 590 http://www.irs.gov/pub/irs-pdf/p590a.pdf
So check 1040 Schedule 1 line 15. You have to deduct that amount from your Schedule C Net Profit. That will give you the allowed contribution for self employment & 1099NEC income.
