Contributions from a mutual fund to a donor advised fund require a cost basis

Do contributions held for over a year in a mutual fund to donor advised fund (DAF) require a cost basis?

 

I donated more than $5000 from a Vanguard fund to a Vanguard Charitable Fund. These funds were held in the account for more than a year.  Turbo Tax 21 is asking for the date of donation, the number of shares, and the value at the date of donation.  All of this information is provided by Vanguard Charitable.  Turbo Tax 21 goes on to ask for the date acquired and the cost basis.  I plan to put "various" for data acquired. I am not sure how to answer the question about the cost basis.  

 

This problem was reported last year and apparently was not resolved.
