The new 1040 is 2 pages. However, since you appear to be using the desktop version, you can easily access all forms, worksheets, and calculation pages from your tax return. When you have your tax return open, click on the File menu up top, then select Print. When you have the print dialogue box open, select the option that says ''All official forms required for filing''. This will print your full tax return. See image attached.
If you would like to keep a full copy (with calculation worksheets) for your records, you can choose ''Tax Return, all calculation worksheets'. This will create a PDF file with every page that you can access later.
