For a no in the past, take the present form and add -ni: korini (I didn't do).
Which ending
After the present form, for didn't or haven't
-ni

About this rule
How to tell
Take the present form for that person:
Then add -ni:
The verb itself shows no past; ni carries it.
Why it works
Bangla does not add na (not) to korechhi (I've done). It says korini (I didn't do), the present form plus ni. It answers both I didn't and I haven't.
Korlam na (I didn't do it) exists, but usually means I chose not to.
Good to know
Was and had take na (not), not ni:
Good to know
Ekhono (yet) often comes with it:

Haven't you seen it?

Slips to avoid
The past no is the present form plus -ni.
Start from tumi koro (you do), then add ni.
