A CRD is indicated by filing 2020 Form 8915-E. TurboTax will prepare this form when you answer its questions to indicate that the distribution qualifies as a CRD. Both distributions from the traditional IRA and the Roth IRA can be claimed as CRDs as long as the total does not exceed $100,000.
With regard to a retirement distribution, "disability" only applies as an exception to the early-distribution penalty. When claimed as a CRD there is no early-distribution penalty to which to apply the disability exception.
If you withdrew from the Roth IRA no more than the original contributions in your Roth IRA, which come out first, the distribution from the Roth IRA is not subject to tax or penalty so there is no penalty exception to apply. You would still benefit by claiming it as a CRD to allow the option of repaying the distribution within three years, the same as with the traditional IRA.
