Missed the deadline for the TB tests

Hi everyone,
I hope you are well.
I have recently been reminded that I was suposed to take the TB test and completely forgot to do so. It's been extremely overwhelming having moved to a different country and now having discovered that we missed one of the requirements

1. I have now scheduled an appointment to do so via the IND referal agreement. After having been here for more than a year, is this still the proper process to follow as if you are doing the test within the 3 month period?
2. I have not received any official letter about the missed TB test and I have seen someone on here reporting that they have.
3. I have asked and it seems people are getting letters from the GGD after having arrived here with a scheduled appointment, does anyone know why some people have been getting reminder/appointment letters and some not?
4. We moved here from the UK after having lived there for a year and we had a 3 year residency permit and it states as one of the conditions that would exempt you from taking the test is
> You have an EU residence permit for long-term resident issued by another EU country or are a family
member and were already admitted to another EU country as a family member of the long-term resident.
Does this apply to us?

Thank you!
