Inherited Land Sale

Good morning!

My wife's grandmother passed away and the trust sold some farmland that she owned. We are 1 of 10 recipients receiving a small portion of that sale through 4 payments a year from an escrow company from the man who purchased the land. My wife received a 1099-S but I don't know how I report this on our return. Is this considered an installment sale? I don't know the value of the land when it sold or anything like that and don't quite know where to go from here. The only tax documentation that we received was the 1099-S.

 

Thanks!
