Home Mortgage Deduction 750K limit pro rating

[kshashi]

I have a home mortgage of $1M (say). I got a 1098 saying "Mortgage Interest received" = $40K (say)

But actually home mortgage deduction is allowed only till $750K.

Should I just enter the numbers 1M and 40K in turbotax, and turbotax will pro-rata it behind the scenes?

Or while entering 1098 in turbotax, should I pro-rate it myself and enter mortgage = 750K and interest = (750/1000) * 40K = 30K?

to me, either method works - the amount that is deductible should be the same

Ah - so it means that turbotax calculates all of this in the backend by itself if I enter in the original numbers 1M and 40K.
