Did a back door ROTH last month and a small amount of money is showing in my traditional IRA

In early December 2025, I performed a back door ROTH for the first time last month. I opened up a traditional IRA account with Fidelity and deposited $8k (I am 50 yo) into the settlement account (which was SPAXX).

As soon as the system allowed me to do it (I was checking daily, multiple times a day … it took a couple of days), I changed the settlement position to Cash FDIC deposit), and then I transferred the $8k into my ROTH IRA. The traditional IRA showed 0, which is what it should be. All good for the past month.

Today I saw there is $1.21 in the settlement account of my traditional IRA. I guess the money must have earned interest during the 1-2 days it was sitting in there.

I obviously don’t want any money sitting in my traditional IRA. What should I do? I’m actually thinking I will perform another backdoor Roth, contributing $8498.79 and then immediately move ALL in the funds in the account to my Roth IRA. Thoughts?
