I’m asking if the retirement plan is the same as 401K. I have been asked if I contributed to a retirement plan and wondering if that is the same as 401k. Please let me know

401K is  is a qualified retirement plan that meets the standards set forth in the Internal Revenue Code (IRC) for tax-favored status.
