I received a 1099R from my insurance company. Do I state it was an RMD?

I turned 70 1/2 this year.  Each year I get a 1099R from State Farm.  The gross distribuion (1.) about three hundred and the taxable amount (2a) is about half  of the distriution.  My contribution (5.) was around two hundred.

I never received the gross distribution.  Not sure what it was used for.  The insurance company has not called me back.  It might of paid for the premium that year.

Do I state this is a RMD withdrawal?

Do I indicate it is a full required withdrawal?

Thank you
