If certain forms are not available, you wouldn't be able to file until they become available. 

Please refer to the following article for the forms availability table.  

IRS forms availability table for TurboTax individual (personal) tax products    

 

State forms availability table for TurboTax individual...

Same here.  Did you get through? if so, how?

Would you please clarify do you mean Credit Karma bank account or are using Credit Karma for your income tax return.
