Thank you Bob,
This is a state issue. Wife did not file MFS return when she learned the husband has filed MFJ. She did not want to add that headache given that the ex was not cooperating with the divorce proceedings.
Ridesharing I believe has to do with sharing ride with others to and from work. I am assuming the husband may not have been able to deduct all the credit from the previous yr.
I think both responses are good advice.
Thank you so much.
