How do I report a problem to TurboTax?

I am using TurboTax Premier - Desktop - Windows

Lots of errors this year when letting TurboTax guide me step-by-step:

1.When entering Charitable Donations, it accepts all the information but there is not a "Done" button.  Therefore, when you go back to the Donation summary, the amounts are blank! Exiting the donations section sometimes fixes the problem and sometimes doesn't.  I couldn't figure out the pattern.

2. When I entered rental property income, it said it would ask for expenses later.  It never did!  I went back to expenses manually.  Then, when trying to add a dishwasher as a Rental Property Asset, it insisted on saying it was computers/electronics.  I exited and came back in and it allowed me to enter it as an appliance.

3. One time when I was exiting, the tally at the top said my refund was in the $100.00 range.  When I immediately reopened, it recalculated to be over $1200.  It should have been current at the time I exited.

4.  One time when I opened TurboTax, it said it was updating.  OK, that is good.  It is actually why I had exited and restarted.  However, the update was to INSTALL NC TurboTax.  I DID NOT ask for a state install.  Fortunately, NC is what I will ultimately want, otherwise I would be really upset.

5.  One time when I was opening TurboTax, and it said it needed to restart.  OK. But it just completely shut down instead.
