If you are so far behind in filing your tax returns that you are asking about going back to 2010, you should probably seek paid tax help. It is too late to receive a tax refund for any tax year earlier than 2016, but if you owe tax due, then you still have to pay, and you will be subject to penalties and interest for the amounts owed, on top of the tax due as shown on the returns. A tax professional could advise you about that in more detail.
