It's been a few months but I recall you have to add a 1099-R from the Wages & Income area under the Retirement Plans section. When you get to the 1099-R entries, select add another 1099-R form. The pick I'll type it myself and continue. Pick the type of 1099-R you want to add and Check the "I need to prepare a substitute 1099-R" box and follow the instructions. Once you fill out the Payee and a Gross Distribution, a form 4852 is generated. Look in the "forms" section for it.
Cheers
