You can enter your K-1 yourself and just estimate the amount. Then later when you get the (late) k-1 you're waiting for, do an update/amended return.
For the 2210, you won't have to guess since you know it's about $2000 for the k-1 you are waiting on just use that amount or your closest guess.
If you wait, they'll really sock it to you on the fees.
Good luck!
