How can I access my US entry and exit dates from my old returns

What is the context of your question?    What is your citizenship status? 

Are you a US citizen?    Or are you a non-citizen, and if so, are you classified as a non-resident alien or "resident alien for tax purposes?"

What type of income tax return have you been filing--  Form 1040 for US citizens and "resident aliens for tax purposes", or did you file Form 1040-NR for non-resident aliens (cannot be prepared by TurboTax)?

Save a PDF of the return ... it should be on the form 2555 and the worksheet for the same.
