Transmission stuck 1/4 - 1/2 out of bellhousing when reinstalling

Turn the crank shaft over a couple revolutions with a ratchet and a socket.

Then see if you can depress the clutch. If so depress the clutch and roll the engine over again by hand. See if the trans pops forward.

Don't use the starter yet to turn it over, you may brake something until you get this figured out.
