E-filing Trust Income Tax Return

[David]

I am e-filing a 1041 with tax amount due. Form 8879-F is available which is like other tax returns that are e-filed. However, no e-file payment voucher seems to be available.

What form does the trustee send with payment on 4/15?

If it is Form 8453-F, this form has to be sent within 3 days of e-file acceptance with attachments (check). However, payment isn't due until 4/15.

So I am at a loss as to what to tell the client to use when mailing the check.

Thanks for your help.
