You need to print only the Form 1040 and any other forms and schedules which have tax data entered and can be identified by the Sequence Number located in the upper right corner of the form or schedule. All other paperwork in the PDF of your return are worksheets and other statements that are for your use only.
Print, sign and date the Form 1040. Include with the tax return all Forms W-2 and Forms 1099 that you received which have taxes withheld. Mail the tax return to the address for your state, with or without a payment, as shown on this IRS website - https://www.irs.gov/uac/where-to-file-paper-tax-returns-with-or-without-a-payment
