How to manage old 403b funds

I am 32 years old and have an old 403b with a little over $23,600 from previous job. When I set it up I didn’t really know what I was doing so I just went with whatever sounded safe and contributed whatever percentage got me the best employer match. It’s pretty much just been sitting there growing for the last 2.5 years since I left that job, and it does seem to be doing fine on its own. The management fee for the fund it’s invested in (FID FREEDOM 3060 K6 (FVTKX)) is 0.45%. Should I just leave it as it is, or Is it better to attempt to roll it over to my current 403b or transfer it to my IRA etc?

ETA: the 1-year return on my Roth IRA is 99.41%, the fund the 403b is in has had a 1-year annualized return of 23.31%. Since I have an active 503b which is fairly conservative, I’m trying to decide if it is advisable that I funnel the old inactive 493b into higher risk-higher reward self managed IRA? Unsure what my risk tolerance should be at my age.
