Probably not. When you enter the 1099-R, you have to carefully answer the questions that follow your main 1099-R form entry...those questions ask about that transfer of part (or all) of that 1099-R distribution to charity.
Check your form 1040 carefully to make sure it is not being taxed (lines 15a,b or 16a,b on a form 1040) and that "QCD" is printed next to that line.
If you are e-filing your return, you don't have to send or mail anything additional. However, if you have a Form 1099-R or W-2 that has federal tax withholding reported on it AND you're mailing your return, you would attach those forms to your return.
In general, the IRS knows what to expect on your return. If you directed any part of your RMD to a charity (must have been done by the Account Administrator), the IRS will know that.
Please feel free to post any additional details or questions in the comment section.
