I left a job and was able to roll my pension into a Roth IRA, it was not a contribution how and where do I classify this?

You did a conversion which is taxable. 

You only enter the 1099R from the pension or 401k.  Do not enter it again under Deductions, it is not a new contribution.  

Enter a 1099R under
Federal Taxes on left
Wages & Income
Then scroll way down to Retirement Plans and Social Security
Then IRA, 401(k), Pension Plan Withdrawals (1099-R) – Click Start

By the way, do you realize that converting it to a ROTH IRA made it all taxable now?  Did you mean to roll it over to a Traditional IRA?  Did they take any tax withholding out of it?
