I'd like to get input from multiple tax experts/CPAs as well as other community members.
When performing a 1031 Exchange from 1 relinquished property to 2 or more replacement properties you need to determine the proportioning out the Exchange Basis from the relinquished property across the replacement properties. In TurboTax Premier, there is not a worksheet to perform this calculation. Instead, I chose to use Excel. Unfortunately, it does not seem like you can upload a document into the TurboTax Premier application. Therefore, if I want to "show the math" in how I calculated the Exchange Basis and Excess Basis for each of the replacement properties, I have to file paper based (by mail) instead of Efile.
Has anyone been successful providing a single Form 8824 the summarizes the numbers across the replacement properties WITHOUT attaching any type of support document that "shows the math"? Does this present any type of red flag to the IRS? I really don't want to have to file by paper/mail.
Thanks!
