I had this issue. Write it all down en in a word document and copy paste it. I had over ten addresses and managed to complete it this way. 

They asked for my marriage certificate. Visa should technically be enough, but I don't think all check-in staff are familiar with all visa types. If you can, bring (a copy of) your marriage certificate. It'll speed things up. 
 
Good luck! 

Since you're the spouse of a US citizen (right?) the Schengen travel ban doesn't apply to you. That means you're free to enter the country.

I just had my ir1 interview at a 'closed' consulate.
 
If you have received a cancelation notice but for whatever reason need to travel to the US soon, email your consulate asking for emergency services. We briefly explained our predicament and I ended up having my interview the same day it was originally scheduled. Best thing : no lines, I was the only one there!
 
Obviously their response will depend on visa type and the consular officer's discretion.
