Taxes overwritten?

I've always used Home and Business, but last year I did my 2016 taxes online using Self Employed. After I finished my taxes, I helped my granddaughter do her taxes online using my account. I foolishly just assumed that I had 5 federal taxes on my account as I had with Home and Business. Now my account only shows my granddaughter's taxes. I fear that my tax records were overwritten by her taxes. A very nice and patient TurboTax support person did everything she could think of, including changing my email and password several times, going in through account recovery, etc., but nothing worked. Are my tax records for 2016 erased? I do have a pdf copy, but I was hoping to be able to just import them into this year's forms.
