How do I claim a 1099-R from a Cares Act 401k withdrawal? I do not see an option to spread it over three years as the IRS site claims.

I took money out of 401k, and they took 10% out for taxes already.  However when I claim this income my refund is greatly reduced.  Checking on the IRS site claims it can be spread over three years, however there is no entry I can find in Turbo Tax to accommodate this option
