I tried to move it, but only cracked the door frame. It refused to move,
even after removing the screws on the storm door frame. There was no room
to move as there is no gap between the storm door frame and the entry
frame.


It is not clear just why the door is binding but it seems strange that there
would be absolutely no gap between the two frames. Door frames are not real
high precision assemblies and there is usually some allowance for
mis-alignment and/or sllightly differing dimensions.

I suspect that the solution to your problem will require removal of both
frames and cutting back the rough opening to allow enough space for the
doors and their frames to fit squarely in the opening with the proper
clearances all around. You should not attempt to install them too tightly,
they need small gaps everywhere.
