I FORGOT TO MENTION that the ch341a programmer I used has a flwa in that it doesn't work correctly when not using the 1.8v adapter. When it's supposed to have 3.3v on the data pins, it actually has 5v which could cause issues when working with 3.3v chips. There is a mod, or you can buy version 1.6 which is built properly.
This @Adamant_IT video explains it much better than I could.
