I have being using turbotax for years. I bought the standard online edition, what should I do now

If you are using the same log in your 2018 information will automatically be pulled in to TurboTax and you can just get started with your return.  

Sign in and Choose the First Tab, Personal Info, and start reviewing and/or adding that information (if you are using the same log in most of the information should be there.)  

If you follow the on-screen questions, TurboTax will walk you through the whole process.  Just be sure to answer all the questions and complete each section.  

If you need some help pulling in your 2018 information, here is a link that will provide more details:  Transferring Last Year's Return
