Getting blank scren when trying to add new stock sales on a Mac

I'm using a MacBook Pro (Sonoma 14.2.1) with desktop software that updated this afternoon. I went to add some missed stock sales and I'm getting a blank screen. I have a strong Wifi signal, I'm not running anti-virus software, no VPN, and I've rebooted my router/modem, laptop, and TurboTax software, and still am not able to add new stock sales. If this is a software bug, is the work-around to manually add the new stock sale amounts to a previous entry, even though the accounts are different?
