Sorry sounds like you owe more for the 1099NEC income than any refund you would get from the W2 income. When you have more income you pay a higher tax rate on all your income. The W2 took out taxes like it was your only income. The withholding didn't cover the tax on the 1099NEC. Plus you pay extra self employment tax on the 1099NEC in addition to regular income tax on it.
