why am I beeing required to fill out a 1099-B form?

TurboTax would not require you to fill out a 1099-B Form. Form 1099-B: Proceeds from Broker and Barter Exchange is a federal tax form used by brokerages and barter exchanges to record customers' gains and losses during a tax year. Individual taxpayers will receive the form from their brokers or barter exchange already filled out.

The program may be asking you to enter any 1099-B you have.

Here's where you enter or import your 1099-B in TurboTax:

1. Open (continue) your return if it isn't already open.
2. In TurboTax, search for 1099-B and then select the Jump to link in the search results.
3. Answer Yes to Did you sell stocks, mutual funds, bonds, or other investments in 2020?
   • If you see Here's the info we have for these investment sales, select Add More Sales.
4. Answer Yes to Did you get a 1099-B or brokerage statement for these sales?
5. At Let's get your tax info, choose how you want to enter your 1099-B (import or type it in yourself).
6. Follow the instructions.
