In 2017 I understood that contributions were not limited on Schedule A if your income was under $156,900, which mine was. So I was able to put the full contribution on my 1040. But this contribution exceeded my AGI by around $80,000. I have carried contributions forward in the past when they were limited by the AGI threshold but have never had the situation where my contributions brought my AGI below zero, so I am wondering if I can carry that $80,000 forward into 2018.
