I have one 1099-R form of 2024 which combined two rollovers of 401k to Roth IRA 41397occurred in May and December. I filled in the numbers as below to TTax, but instead using box 2a taxable amount to calculate my federal tax, the software used the gross distribution (box 1) to calculate. This leads a large tax due
box 1: 130000
box 2a: 41397, 2b not checked,
box 5: 62885 (this is my after-tax contribution to my employee's 401k plan when I was working a few years ago and now retired)
box 7: G and all the rests are blank or 0
I called Vanguard preparing 1099-R and was told box 2a is correct, although I thought box 1= box 2a + box 5.
For my case where box 1 is not equal to the sum of box 2a and box 5, TTax seems cannot use the right 2a for calculating federal tax, any suggestions, thanks
