From Rover's Website:

Will I receive a 1099 from Rover?

Whether you receive a 1099 from Rover will depend on how you’ve withdrawn your Rover funds and how much you’ve withdrawn. Here’s how it breaks down for sitters/walkers:

If you’ve been paid out over $600 via check over the course of a calendar year, Rover will send you a 1099 tax form.

Note: Rover does not handle tax documentation for redemptions made via PayPal, as per IRS rules, the entity that distributes these funds to you is responsible for generating these documents, as appropriate. To learn more, see this IRS document, 2018 instructions for Form 1099-MISC. If you redeem your earnings through PayPal, then PayPal will handle your tax documentation in accordance with its own tax reporting practices. For more information, see the PayPal article How does PayPal report my sales to the IRS? Will I receive a 1099 tax statement?

Rover doesn't issue them to individuals yet, you may find the template to file by yourself all over the web, that's what I've found googling for the https://1099-misc-form.pdffiller.com/ (form 1099-MISC online) but you all the way need the Rover's credentials in order to do so
