I moved abroad in 2015 and didn't realise I needed to file as I wasn't earning in the US. I need to file for years past and this year but don't know where to start?

TurboTax can guide you through the process. You can complete this year's return by the 15th of April, then you can work on the years you missed. If you are expecting a refund for 2015, you will need to hurry. April 15, 2019, is the last day to file your original 2015 tax return to claim a refund.
