If you want or need to aggregate any businesses, the return is still print and mail only in TurboTax. TurboTax is working with the IRS to enable e-file for aggregated QBI businesses and the QBI netting/carryforward worksheet, but no date has been given for when e-file will be available.
Once you aggregate, you must continue to aggregate in future years. But, not aggregating last year does not preclude you from aggregating this year. Refer to the IRS instructions for Form 8995-A for more information on aggregation.
