Student-Dependent IHS Expiry Date?

My fiance and I currently are applying for her Student-Dependent visa.
On the page where it asks my fiance for her details for the immigration healthcare surcharge, it requires her to enter my visa expiry date. As I do not yet have a visa and we are applying together, we are not sure what to enter in this field, but it is required and we cannot leave it blank.
Should we enter the end date of my course? I am not sure how to proceed.

I am in the same situation right now. Can you suggest me, What should I enter visa expiry date?

Hello! My wife and I entered my course end date as listed on my cas statement for my wife’s visa expiry date, and her visw was approved.
I don’t know for sure, but my feeling is that this question is simply there for the purpose of calculating the IHS fee.
Wish you the best of luck!
