I'm also using Premier. Contact Support and let them know you can't generate multiple IT-203-F Schedule Bs? I had to deal with a bunch of issues with Form 2210 last year, and I was finally routed to a tax preparer/CPA that was able to confirm the issue and a future update fixed the issue.
If you share your screen with Support, the instructions in Step-by-Step mode clearly state that multiple Schedule Bs can be generated by scrolling -- that doesn't work in the Windows version either. That text alone should be enough for them to open an internal bug report?
