@Shilpa9 In my area in California, Airbnb remits taxes to the county on a monthly basis. I still need to fill out a form, which I do online, indicating the amount that Airbnb has collected. Prior to Airbnb collecting the TOT, I had to fill out the form with a payment.
The information that Airbnb has posted online in their help article only mentions Texas state taxes, so if your county also requires a tax, apparently Airbnb has not yet made an arrangement for that. In many states, notably Florida, Airbnb does collect state and county taxes.
I would advise, when you talk to anyone from the Texas Comptroller's office that you ask to speak with a suprevisor since sometimes lower level employees sometimes don't know what is going on.
I don't remember if I previously sent you this link, but if not, here it is again:
