Schedule E is a tax form that asks information about certain rental and royalty income, real estate investments, and pass-through business income. It gets attached to your main tax return, Form 1040.

In addition to the updated 1040-ES tax forms and instructions, it also offers a range of other tax resources on its website.

In addition to form 1040-ES, the IRS has released Publication 505, Tax Withholding and Estimated Tax, (downloads as a pdf) for 2018.
