Will this lid fit K4436?

Yes, I bought this to replace the lid of my K4436 and it appears to be identical. I would note that this is a white version of the lid since I think K4436 comes in multiple colors.

Is it returnable if it does not fit?

Probably not. I do not see anything on this listing that indicates returns are accepted if the toilet lid does not fit.

Will this fit k-4421 tank ?

I do not know. Mine is a standard size and it would not fit . I had to go a plumbing supply place to get a used one
