So it sounds like it went from a 401K with the company to an IRA with Merrill Lynch.
If so you will get a 1099R that needs to show this. It would not be taxable if it goes from a Traditional 401K to Traditional (non-Roth) IRA.
TurboTax will ask if it rolled over and if it was a Roth. If not, it will not be taxable.
