I did make the mistake of entering $5000 as an excess contribution which caused the error but I also went in and fixed it to say $0. Turbo tax still created the IRA contribution. Because the excess contribution was the same dollar amount as the non deductible previous year contribution, it appeared as if Turbo Tax was allowing the conversion (wrong!). I had to go to the IRA worksheet and manually clear the excess contribution to actually clear the $5000 since reentering as $0 didn't clear it. Hopefully the same method works when doing an amended return
