I'm now forced with recreating this piece and don't
know how to make a tongue and groove joinery. The wood is probably 1/4
inch thick by the way if that matters and the tonge and groove is very
thin. Help!!

Hum - the traditional way to do that would be to use a match plane.
There are router bits for T & G, but I don't know that any of them
would handle 1/4" stock.

If I were trying to do this, I think I'd use the table saw to cut
a 1/8" kerf (or 3/32" if you have a narrow kerf blade) to serve as
the groove, and a rabbet plane to cut the tongue.

If you need to match the existing T & G, and that has a groove
narrower than your saw's kerf, I'm not sure what to do. If it's
wider, of course you can take two passes to make a wider kerf
(incidently, this calls for a zero clearance insert and a feather
board, & I'd use a sacrificial fence, just for safety).

If the existing T & G has a bead or other ornament alongside the
tongue, a scratchstock or a hand-beader will serve to duplicate it.

I made a run of thin T&G recently. I ended up with a thickness of
about 3/8". I used stacked 2 wing slot cutters on the router to cut
both the tongue and groove. it worked fine.
