Can you help me get access to my sister-in-laws turbo tax account so I can complete her 2016 return before Oct. 15th she passed away and I am the trustee of her estate?

My sister in law passed away before she completed her return. She uses turbo tax. Can you help me get access to her account so we can complete her return before Oct. 15 and so we have access to her prior information for completing her return.
