Is an IRA conversion (401K-IRA-Roth) listed under "outstanding rollovers" on the page that asks the value of my IRAs as of 12/31/19?

An outstanding rollover is one where a distribution is made from a traditional IA before year-end but the rollover contribution to a traditional IRA was not completed until after year-end such that the this traditional IRA money was not included in the year-end balance of either traditional IRA.

In your case there is no outstanding rollover.  Neither a 401(k) to traditional IRA rollover nor a Roth conversion can result in an outstanding rollover because the account on each end of an outstanding rollover must be a traditional IRA account.
