Large number of w2g's in 2021 desktop cause system to get slower and slower, then finally non-responsive

I have around 30 w-2g's to enter.  After 10 w2g entries, the systems slows down significantly.  It keeps getting worse until it is totally non-responsive.  It takes about 2-3 minutes for a simple field to populate and move to the next field.  I spent over 8 hours over 3 days with multiple TurboTax support reps, and no one had an answer.  We tried everything.  My system is current (I even bought a new laptop after one rep told me I was the issue).  I've never had this issue with past TurboTax versions or years.  I can enter in summary (10 w2g's summarized as one entry), but the IRS recently returned my 2019 return with a huge bill.  When I finally talked to them, they said I had to enter every w2g separately so it matches what they have.  I like TurboTax, but it becomes non-functional with this issue.  Do I have any other options other than switch to TaxCut?
