Can someone tell my why ProSeries ignores box 5 for Employee Contributions? Govt website (opm.gov) makes it very clear this amount is not taxable but I can't make ProSeries deduct it if I enter everything exactly as it is on the 1099-R. I finally just entered the box 2a (taxable amount) figure myself. The 1099 itself does not specify an amount for this box. It just says "Unknown."
