Tax Year Prior to 2020: How to import Online in Turbo Tax the Form 1099 from TD AmeriTrade and 1099K from AMAZON online selling from self employed Business ?

The 1099-K is not a required form to be entered into TurboTax. It is an information return sent to the IRS and a copy to the merchant prepared by Amazon and other businesses that showed merchant credit payments processed. 

For importing 1099-Bs follow the instruction below:

1. Open (continue) return if you don't already have it open.
2. Inside TurboTax, search for 1099-B and select the Jump to link in the search results.
3. Answer Yes on the Your 1099-B screen, then select Continue. ...
4. Select how you want to enter your 1099-B (import or type it in yourself) and then follow the instructions

Hi,

Thanks for reply with the solution to Import the 1099 from the TDAmeriTrade . For the same I found in the Link in the Turbo Tax itself and it is done.

But now I am unable to do the same for the 1099-K  Recd. from the Amazon Payment, Inc. for selling goods Online. As this topic falls under SELF EMPLOYEED-Income, I could not find the link to Import the same into Tubro, though I have the Physical Documents with me.

Do I need to fill in the details manually or is there any way to import the same into TURBO.

Please advice, Thanks,

No you don't enter the 1099K.  Yo just enter your total self employment income on Schedule C.
