Is Texas state teacher retirement payments considered an RMD

[DS30]

You will meet the RMD requirements related to your TX state teachers retirement distributions (see below)

Since the IRS requires the reporting of all RMD payments relates to all qualified plans (and your TX state teacher retirement plan falls under this category), the system will still ask about RMD (even if it does not apply to your pension distributions).

Therefore, 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)
