I thought that I had the funds from my previous 401k rolled over to my new 401k, but it turns out that never happened thanks to some paperwork mistakes. Once I received my 1099-R saying I was the recipient of those funds, I called the retirement company and found out they mailed me the check in July 2017 but I never received it. They will be reissuing the check to me, and I plan on depositing it into my current 401k, but I don't know how to claim or report it. To the IRS it looks like I cashed out even though that was never my intention and those funds will ultimately go into my 401k.
