Hey there, @felorivera.
I hope all is well on this beautiful Monday morning.
Great news, you can run the profit and loss and customize the dates to the year 2018. Let's get started.
1. Open the Reports menu.
2. Type Profit and Loss in the search bar in the top right corner.
3. Choose the first option on the list drop-down that says Profit and Loss.
4. At the top of the report, customize the dates to the year 2018.
5. Select Run report.
That's all there is to it. Please let me know if you have further questions or concerns. I'll be around the corner should need more assistance. Take care and have a great week ahead!
