You may have to call (or ask question at web site) Ohio Dept of Taxation (ODT) for an answer. I have not seen your situation addressed before.
I'm of the opinion (but that's all it is, an opinion) that you still qualify for reciprocity because you were a resident of reciprocal states, all year. The wording in the instructions is not that you have to be a full year resident of A reciprocal state, but only a full year non resident of OH, and a reciprocal state resident. From page 10 of the instructions:
"A full-year nonresident living in
Indiana, Kentucky, West Virginia, Michigan,
or Pennsylvania does not have to file if the
nonresident's only Ohio-sourced income is
wages".
You were a full year nonresident of Ohio living in KY "and" (not "or") PA.
I interpret "My work is work from home in the state of Ohio" to mean you work from home (in KY & PA) for an OH employer. In that case, the reciprocal issue is moot. Since you do not physically work in OH, you are not subject to OH income tax, regardless of your home state (reciprocal or not).
