Dumb question - remitting backup withholdings

[BulldogTom]

OK, so I got one of those letters from the IRS that says we have a mis-match on the ITIN number for a 1099 payment. This particular payment is for rents. We checked our W-9 and the number we submitted is what the landlord gave us. So we sent the first notice B. No response from the landlord yet and the time is running out.

I have never had this happen before. I have only sent one Notice B before, and they got right back to me. So if we start withholding, where do we remit the money? Is there a quarterly form or something?

Thanks for the help
