Aircraft X; on vector with ZZZ approach. Sector X calls to coordinate the helicopter on Victor route XX; instead of the filed route Victor route XY. Then approach called back approach request direct ZZZ1; I approved it. I approved it not noticing that the equipment status was /A [Aircraft equipment suffix].I called approach back saying I needed the helicopter on the airway not specifying what airway. I notice approach vectoring the helicopter to the south back towards Victor XY. Not realizing the altitude 4000 was in the 4200 Minimum IFR altitude (MIA). I called approach and said I can't take the helicopter until established on the airway. I had also forgot the MEA on Victor XY is 4500; until a minute or so after the helicopter was established on the airway; then I climbed the helicopter to 5000 then issued the approach clearance into ZZZ1.Aircraft filing Victor XY to start an approach into ZZZ1 are infrequent; I had forgot the MEA on the airway. Also I should have been more specific during my coordination and or call approach and ask what was going on.
Center Controller reported reneging on a handoff for a helicopter that was off the filed airway; below the MEA; and the minimum IFR altitude.
