Covid 19 401k withdrawal

So I had a 1099r for an early distribution. My question is two fold. Firstly if I wish to claim the distribution ratably do I just divide the total amount by 3 and ONLY claim that amount for this year regardless of the total distribution listed on my 1099r? Secondly, TurboTax is not currently offering an option to waive the 10% penalty which was covered in the CARES act, when will that be resolved?
