Hello! I want to add my crypto profit gains and having trouble. I'm currently using zenledger and they produced form 8949. How do I add that into turbotax?

you can't.

your choices

re-enter all the details on the Turbotax form 1099-B worksheet

or

enter summary totals on the worksheet and then use form 8453 to submit the 8949 to the IRS

read the instructions for filing

https://www.irs.gov/pub/irs-pdf/f8453.pdf

 

What Box Category?

It should be C and/or F if they don't give a 1099-B.

if you enter a summary of Box C or F, TurboTax should prompt you to attach that Form 8949 showing your transaction details. It must be a PDF file.

 

then you can e-File it all at once.

If not prompted, you'd have to mail it separately as suggested above.
