Thanks for the reply. Unfortunately, the origination date and outstanding mortgage principal are not available. Because this is a coop, not a single home mortgage, I share a portion of the mortgage interest for the whole building with 900+ members of the coop. As far as I know the mortgage could be in the millions. This is the reason for the CPA letter giving me my portion of the interest based on the number of shares I own. The CPA letter is a standard letter providing the interest on a per share basis. All coop members receive the same letter (the letter is actually posted on the coop website). The letter actually states that it is to be used for personal deductions on our tax filing. This similar letter has been used since 2008 when I purchased the coop, and I had no problem filing my taxes with it, except this year when I decided to try TurboTax.
I've tried all the options suggested by the expert community, including your suggested steps, I am unable to complete the entries for any of them due to the missing information.
