My dad passed back in January and had a thrift savings plan (TSP). My portion is about 72k. I am probably going to put it in an inherited IRA and not take the lump sum. I do have a few questions.

What can I expect as far as interest rates go? Are there different options for me to invest in?

I know I have to take out money within 10 years but is there a minimum amount of time I have to wait before withdrawing money?

Are there any hints or tips that people have for this?

Really I am look looking to avoid that initial 10% hit from taking the lump sum. My wife file jointly. We make about 180k pre tax with three kids.

Thanks for any help and advice
