For the state of Ohio, do I need to include the amount from my Thrift Savings Plan as a lump sum retirement credit if I withdrew the full amount in 2018?

Claiming a lump sum credit is optional. You can decline it. if you claim it, you have  to give up any future retirement income credits (up to $200 per year).

Many people who ask about it are not eligible. For example, leaving your employment and cashing out your 401k  or TSP does not qualify.

 There are two separate OHIO lump sum credits. One, the "Lump Sum Distribution Credit is only for people over 64 and you must have taken out everything in the company plan  and you must have left the company.

 The other, the Lump Sum Retirement Credit, is for any age but you must have actually retired from your company, and taken your entire account as a lump sum.
