Yes, the Trial Balance feature under the Accountant Tools in QuickBooks Online Accountant will be discontinued effective on May 31, 2019. However, this will be replaced by the new Prep for taxes feature. Accountant's Trial Balance (ATB) software link into ProSeries 2020 business tax returns is NOT currently working.  This feature allows for business trial balances to be seamlessly imported into business tax returns.  It saves me an amazing amount of time, since the links carry forward every year.
