can I claim safe harbor for renting (through AirBnB) part of my house while traveling?

[Critter-3]

There is no such thing on a Sch E.

Thanks for the prompt and clear response!

along the same topic, I understand however that I can claim QBI for it, correct?  

[Critter-3]

I highly doubt it rises to the level of a business to take the QBI deduction.  

Can I get the QBI deduction on rental income?

Qualified business income, or QBI, is the net income generated by any qualified trade or business under Internal Revenue Code (IRC) § 162.

Rental properties are usually treated as passive activities, and passive activities are excluded from the definition of a qualified trade or business. However, rentals that qualify as trades or businesses under IRC § 162 are not considered passive, which means they could potentially qualify for the QBI deduction.

To provide preliminary guidance to this popular question, the IRS released Notice 2019-07, the key points of which we've summarized below.
