Can amend prior year (2014-2016) to change from MFJ to HoH?

A married person can not file HOH. Your only choices are MFS or MFJ.

Actually, a married person can file as HOH under certain circumstances.. However, once you file MFJ, you cannot change that after the extended due date of the return. The only exception is if you were not legally married,
