Year End withholding - Form 945?

[Guest Key Lime Pie]

How to submit withholding amts from a ps plan is a new concept for me, as i have just determined one of my plans' new investment company does not submit the withholding amounts. Apparently they are still sitting in the trust and it is for me the consultant to determine. Since the total amount is under $2500, looks like they can file form 945 and 945-V and mail in a check to 'United States Treasury'. Can i just be sure, there is nothing I need to do by this Friday, year end 12/31/10?
