Are these sites participating in the universal notification day or not, when did you apply, and when did their deadline close?
I scanned my emails from my postdoc year and mid to late January is when I started to hear back about statuses and interview invites.
If these are programs that had a 1/1/23 deadline, I might wait a little longer since they may still be reviewing applications and will likely do interviews in February.
If these are sites had much earlier deadlines, a brief inquiry email to the Training Director seems very appropriate. Good luck!
