We are getting a refund from Federal of 411 but when it printed out a copy there are 4 payment voucher for 518

[ThomasM · Accepted solution]

If the vouchers have the form number 1040-ES, then those are for quarterly estimated tax payments.  Unless you're self-employed or have significant income from sources (non-W2) where tax is not withheld, then you can shred them since they won't apply to you.

Those forms are printed as a convenience; you're not required to use them.
