Mistakenly filed as Indiana resident in 2018. Did not file a Kentucky return.
Helping my boyfriend with this years taxes, when it prompts for his 2018 tax liability I was unable to find it because, come to find out, he filed as an Indiana resident and didn't file a 2018 KY state tax return at all. How do I fix this? These states have a reciprocity agreement, and I don't know if that makes it any more complicated.
