Where do I file Schedule K1 after already filing?

So I filed my tax return a while ago but I recently received a Schedule K1 for a partnership I'm a part of. I know how to amend my tax return but for the life of me I have no clue where to enter the K1 information. I looked up a tutorial and it tells me to file it under a S-corps-partnerships and trust section but its not showing up for me.

 

I'm running out of time and this is really stressing me out, any help with this would be greatly appreciated.
