Can I duplicate my 2018 tax return?

Unfortunately, you are not able to duplicate your income tax return.

Can I create a new tax return and import my data from another tax return? I want to use it to run some "what if " scenarios for the coming year.

Yes, you are able to create a new tax return but you cannot import 2018 into a new 2018 return.  You would need to start from scratch.
