Received a 1099-R for state retirement payment. This is a payment received each month, for a plan paid into for many years. The turbo tax is asking for what percentage of this is MRD. How do I figure that?
You will meet the RMD requirements related to your employer pension plan distributions (see below)
Since the IRS requires the reporting of all RMD payments relates to all qualified plans (and an employer pension plan falls under this category), the system will still ask about RMD (even if it does not apply to your pension distributions).
If you are asked a question about taking an RMD (because you meet the age requirements) from your pension when entering your pension information, the answer is "yes" that this withdrawal was an RMD and that all the distribution was an RMD (screenshot).
