schedule k-1 PTP

craff

I bought a stock through robinhood without knowing it is PTP k-1.

And, it is Publicly traded partnership (PTP).

So, freetaxUSA refuses to file my tax.

Questions:

1. i haven't sold the stock yet, but received the schedule k-1. do i need to include it in my current tax?
2. Anyway to get around such as using a different software? what is it?
3. or, i can do ammendment after filing it? using excel , what to compute?

thanks
