You are correct that for the purpose of the Worksheet in IRS Pub. 963, use the % of Mortgage Interest for House A that you would claim as an Itemized Deduction on Schedule A.
The balance of the Mortgage Interest for House A will be claimed as a Rental Expense on Schedule E.
If you enter the total Mortgage Interest for House A in the Rental section first, along with available rental date, TurboTax should calculate the % of interest to move to Schedule A for you.
