Yes, you should mail the necessary forms to the IRS as soon as possible after filing your tax return. You have until April 18, 2017 to mail the forms, but your return may not be processed until the forms arrive. In other words, yes, failing to mail the forms in a timely manner may delay any refund you are expecting.
