Medical Insurance bik tax relief question

2 questions:

1-) Can I claim dental insurance bik with medical insurance bik (eg. adding sum of dental bik to medical bik and type it as total as tax credit) as tax credit or only medical insurance is allowed as part of tax credit?

2-) I had 2 employers in 2020, both of them got me in medical insurance. On Revenue website it asks me to choose employer to add medical insurance tax credit relief but it lets me only choose one. Isn't it possible to add both employers separately? After I add one of the medical insurance, there is no chance to add another one. Am I missing something?

Thanks!

Bik and tax credits are not the same thing, Bik is taxable income, ie what your employer pays on your behalf and should be taxed at source by your employer.
Tax credits are 20% of your taxable amount upto €200, dunno if there is a tax credit for dental.
I'd add both, again dunno about dental insurance, and put a note to explain.

If you have any other health care and specific dental, not routine, that haven't been covered by your insurance you can claim those and Revenue will give you a tax credit of 20%, figures must less any amount coverd by insurance
