Reserve documents? : Veterans

What document will show my dates of service in the Air Force Reserves? I have a prospective DoD employer that is asking for them. I deployed in 2016, so I already have a DD214 for that service, but my total time in the reserves lasted until 2020. They are asking for some type of documentation that shows that. I have already checked the VA letter generator, but that only shows my active duty time. And I checked the DPRIS site on milConnect but that does not show any forms with my ETS in 2020 on it anywhere. On the VA.gov site, they have the correct service dates for my reserve time, but I can’t find an official document anywhere that shows that. For now, I just printed off my profile page that shows those dates on VA.gov but I’m not sure they will accept that as official documentation.
