Add your W2 box 1 and your Net Profit on Schedule C minus the SE tax I explain below. And are you married?
If you have self-employment income you can only contribute up to your net profit reduced by the deduction allowed for the ER portion of your self-employment taxes. See IRS publication 590A (page 39 for ROTH) https://www.irs.gov/pub/irs-pdf/p590a.pdf
So check 1040 Schedule 1 line 14. You have to deduct that amount from your Schedule C Net Profit. That will give you the allowed contribution for the 1099Misc income.
And make sure the Schedule C and ROTH Contribution are entered for the same person if you are married filing Joint. Or maybe you have a penalty for having too much income to contribute.
See IRS publication 590A (page 39 for ROTH) to see if you are allowed to contribute to the ROTH IRA.
