You can ask your clinic for advice, but it's probably going to be up to you to figure out, mainly because you have to work it around your schedule. It can seem complicated at first, but you get used to it. I take a multivitamin with iron plus an additional iron supplement, calcium 3x/day, B12, biotin, and D3. Calcium and iron are supposed to be at least 2 hours apart, and I also take a prescription thyroid medication that's supposed to be 4 hours apart from calcium and iron.
I use a free app called Medisafe to track my medications and remind me. It's really useful because you can track what time you took everything, and it also tracks how many of each you have left and reminds you to refill. You can set reminders at whatever time you want. I set reminders as follows, but I usually stay ahead of schedule.
6:00 am - Thyroid prescription
10:30 am - Multivitamin with iron, B12, Biotin, D3
1:00 pm - 1st calcium
3:30 pm - iron
6:00 pm - 2nd calcium
8:30 pm - 3rd calcium
I also recommend getting a pill organizer with 3 or 4 compartments for each day, where each day has its own removable box (the one I have looks like this one: https://smile.amazon.com/Organizer-Compartments-Moisture-Proof-Medication-Supplements/dp/B07Q9JSHMP). I distribute my pills in that once per week, and then I can just grab the box for the day.
