The returns have not posted to the Filing Archive yet. I believe the first month Avalara was able to file for us was November. On the liability worksheet I see more states listed than just the states I marked as having Nexus.
When in the admin console click Tax Returns>Avalara Returns Calendar
Here you will find all states and jurisdictions in your filing calendar, which is where we will be filing for you.
If you have states that are missing in here please email the filing calendar information we need to file for you there to firstname.lastname@example.org and we will add it to your filing calendar.
