First, it would be helpful to know what Forms 1099-R you received from the pension plan and the code in box 7 of each of those forms. This will identify the type of rollover, direct or indirect.
Also, did the distribution from the pension plan in July occur before or after your separation from service in July?
The date that you reached age 70½ in 2019 does not matter. With respect to RMDs, what matters is that you reached age 70½ on some date in 2019. Because you reached age 70½ at some point in 2019 and you were no longer employed with this company at the end of 2019, any distribution from your pension plan in 2019 was RMD for your pension plan until the RMD is satisfied and that money was ineligible for rollover to the IRA. Had you not separated form service with this company until after 2019, the still-working exception to taking RMDs from the plan would have applied, but this is not the case.
