PROBLEM SOLVED!
What I did not know, and my custodian finally share with me, is that I should have registered a new EIN just for the IRA on the IRS website. Didn't know I could do that, and it took all of 5 minutes. Once I had the EIN, I provided my Property Manager with this and he completed the 1099 using the ROTH IRA's EIN, not my SSN. I may now have to complete a 990-T form (Exempt Organization Business Income Tax Return) to match up with the 1099-MISC.
