I did Lyft for few weeks in 2020 therefore my income is lower than 20,000 due to which i did not receive 1099-K. Which Form should I use in turbotax to report my few $?

You can use Deluxe if you choose not to take expenses. However, even if you earned less, you may still want to upgrade to Self-Employed to take any expenses.

Thanks for your reply however i am wondering if you can tell me what Form should i use to upload my LYFT details in Turbotax?

Most Lyft customers can import their information from Lyft. Use these instructions if you prefer to enter them yourself.

Most of what you need is provided in your Lyft account on your Lyft Tax Information page. You can also sign in to your account, look under the Driver heading, and select Tax Information. It’s okay if your Tax Info doesn’t include everything listed—not all drivers have the same forms and expenses.
