Since box 5 on your CSA-1099-R can hold more than one item, tell us how much of your box 5 is for health insurance. How do I know? Where is box 5 information explained?

TT is asking for me to put in Health Insurance Amount from box 5 that contains more than just health insurance. Where would I find out how much is just for health insurance vs Employee Contributions/Designted Roth Contributions?
