Similar question regarding form 5695

I understand they are working on the issue to fix this by March 26th. I tried to refile after the previous date of March 17th and still rejected. I also unchecked the joint occupancy box and it still failed. I am a joint occupant, unmarried filing separate.  We co-own the home and split expenses where he pays for the house and I pay all the other things like insurance, cars, food, utilities and insurance. I also paid for the entire home improvement and want to claim it on my return. Will this repair fix the issue or should I print the forms and include a statement regarding this matter. My partner has already filed and can no longer file a form 5695.  Please advise.

Thanks
