No. I think you did a rollover or conversion to the IRA. It is not a new contribution. Did you get a 1099R? What code is in box 7? How did you put it in the IRA? Did you get a check and put it in the IRA within 60 days? Or did the 401K transfer it directly?
If you rolled it into a Traditional IRA (not a ROTH) then it should show up on your 1040 line 5a and 0 taxable amount on line 5b with Rollover written by it.
