IRA box does not have an X in it

I recently rolled over an employer 401K plan in to a traditional IRA at Vanguard.  When rolling it over (at the end of 2022). they said I was required to take my RMD for 2023, so I took it and received it.  On the tax form I just got from Vanguard, they show distribution code 7 but the IRA/SEP/SIMPLE box is not checked.  Because of this, this distribution shows up under Pensions and Annuities on my 1040 instead of IRA distributions.  Is that correct? I would think not, but didn't know if I should just make an X in the box on the online software.  

 

Thanks!
