Would I have to wait until the next fiscal date, which is in 5 months for a reclass spot?

If there is no class seat then there is no class seat. 95% of the class seats go to initial entry Soldiers and only a tiny amount go to reclass. A 92Y class seat could pop up tomorrow or not for another two years. You might never be eligible to take one when it's available, or there may never be a class seat available when you're eligible to reclass to it.

Either:
1 pick a handful of jobs yo are willing to take
2 pick a job the Army always needs like 17E,
3 join the Reserve Component and reclass wit them (it may take two years to go to school)
4 pick something else and PCS away

I did a search and it appears that you are in a Reserve unit. Have you done the legwork and contacted other units to see if they have an open spot for a 92Y, and contacted the unit about transferring? You should also talk to your unit training NCO to see if there is any update on a seat in a class.

You may have to wait until your reenlistment window opens and use that to get an MOS change.

This process can vary largely depending on if you’re either Regular Army or Guard/Reserves.
