For the Massachusetts Student Loan Interest deduction, how do you specify undergraduate interest if you've consolidated graduate and undergraduate loans?

[CarolynM]

You have to manually apportion between the two. 

For example, if you consolidated learn is for $100,000

$25,000 for undergrad, $75,000 is for grad.

You would apportion interest paid 25% to undergrad and 75% to graduate

Massachusetts does accept approximations for this deduction.
