The IRS considers undocumented cash income (no W-2 or 1099-MISC), for work performed, to be self employment income. Enter at "Business Income & Expenses" and TurboTax (TT) will complete Schedule C or C-EZ 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 $400. You report the income from your own records, , no matter how weak those records are and even if they consist of nothing more than your memory.
You cannot use the free version of TT.
But,
TurboTax also has another free product called the Free File Edition (not to be confused with the regular Free Edition). It has free Federal preparation and free State preparation. There is no efiling fee. It is not available after October 15
The Free file Edition can handle a 1099-MISC.
The Free file Edition is more fully-featured than the regular Free Edition. The Free File Edition can prepare Schedule A, C, D, E, and F that the Free Edition cannot.
For Free File Edition a user needs to meet only ONE of these qualifications:
- AGI of $36,000 or less
- or active duty military (including Reservists and National Guard) with a military-issued W-2 and a 2019 AGI of $69,000 or less
- or eligible for the Earned Income Credit (EIC aka EITC).
