1099r inheritance- where do I input this information?

My husband received a lump sum that has a taxable amount in box 2a however box 4 says there is no federal income tax withheld. It does show 4D in the distribution code but IRA/SEP/SIMPLE is not checked.  There is an amount in State tax withheld. I've never had to input this before so I'm not sure where exactly I need to fill in this information.
