"Transmission Trouble" and "We're Having Trouble Printing Your Return"

I think there is a problem with the transaction amount causing these errors.

 

I am able to view my returns by clicking "View Your Return" in the section before e-filing where it says to double-check your name, SSN, and birth date. Is this sufficient to file by mail?

 

If not, what are my options to get my return completed? I saw this post, but was told that neither of these options are recommended by TurboTax. Also, the number on that post is a dead number.

I was then told to try to file by mail.

 

A lot of my transactions are short-term gain/loss $0 trades. Is it ok to just delete those to lower the transaction count?
