Are you sure the jobs you worked were W-2 jobs or did you just work for cash?
The IRS considers undocumented cash income (no W-2 or 1099-NEC), for work performed, to be self employment income. You report the income from your own records. Enter at "Business Income & Expenses" and TurboTax (TT) will complete Schedule C for you and allow you to deduct any expenses associated with this income. You'll also have to pay self employment tax (social security & medicare tax) on any profits greater than $432.
