In response to your question regarding the number of times your return can be rejected, I don't know about this year, but mine was rejected last year half a dozen times before I gave up and mailed it on April 17. Mine was rejected with out explanation, but the only reason I could determine was that I could not enter identifying information (DL, pin) for my late husband who had passed away in the middle of the tax year. Since he was identified as deceased, the system had no place to enter his information, but it wouldn't be accepted without the verification. I couldn't get anyone on the phone at TurboTax to either tell me how to work around it or to explain it.
Since I mailed my return, I had to wait until September for my refund, which I received with interest (which is taxable this year, thank you very much!!). It never did identify as received in the "Where's my refund" system, by the way, until the day the refund showed up in my bank account.
