A previous answer from shellsbush180 indicated that the answer to this exact question was "no". But this implies that a 401(k) is excluded from calculating a RMD. I that were true, why would anyone convert a (no basis) 401k to an traditional IRA, if the 401(k) was able to grow indefinitely, with no required distributions?

If you are not still working for the company then the combined 401(k) and Traditional IRA RMD amounts would be exactally the same total amount as it would be if all the money was in a Traditional IRA.
No it is not.
Use Form 8606 to report:
Nondeductible contributions you made to traditional IRAs;
Distributions from traditional, SEP, or SIMPLE IRAs, if you have ever made nondeductible contributions to traditional IRAs;
Conversions from traditional, SEP, or SIMPLE IRAs to Roth IRAs; and
Distributions from Roth IRAs.
No, a 401k tax deferred account is not entered on a Form 8606 Nondeductible IRAs.
As stated on the instructions for the form 8606 - https://www.irs.gov/pub/irs-pdf/i8606.pdf
Purpose of Form
Use Form 8606 to report:
- Nondeductible contributions you made to traditional IRAs;
- Distributions from traditional, SEP, or SIMPLE IRAs, if you have ever made nondeductible contributions to traditional IRAs;
- Conversions from traditional, SEP, or SIMPLE IRAs to Roth IRAs; and
- Distributions from Roth IRAs.
What types of retirement plans require minimum distributions?
The RMD rules apply to all employer sponsored retirement plans, including
profit-sharing plans, 401(k) plans, 403(b) plans, and 457(b) plans. The RMD rules also apply to traditional IRAs and IRA-based plans such as SEPs, SARSEPs, and SIMPLE IRAs.
The RMD rules also apply to Roth 401(k) accounts. However, the RMD rules do not apply to Roth IRAs while the owner is alive.
Form 8606 has nothing to do with determining the amount of RMDs. Form 8606 Part I has only to do with determining the taxable amount of IRA distributions, regardless of the reason for taking a regular IRA distribution, and nothing to do with 401(k) distributions.
For the year that you reach age 70½ and subsequent years, RMDs are required from 401(k) accounts, except if you are still working for the employer and you are not a more-than-5% owner of the company. An RMD from a 401(k) is required to be satisfied from that 401(k), without regard to any other qualified retirement accounts. You are required to satisfy any RMD required of the 401(k) before rolling over any other amounts distributed from the 401(k).
Like money in a traditional IRA, RMD requirements make it certain that money in a 401(k) account will eventually be distributed. Nobody can live and work forever to maintain the still-working exception to RMDs from the 401(k). Even if the employee dies while still working, the employee's beneficiaries will have to take distributions from the 401(k).
