How much Net Profit do you have?
For self-employment income 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 27. You have to deduct that amount from your Schedule C Net Profit. That will give you the allowed contribution for the 1099Misc income.
