cani ignore 1099-R box 4 instructions say attach copy B. I do not have an e copy

If you are e-filing and have entered Forms 1099-R that have an amount in box 4, TurboTax automatically includes in your e-filing the details that you entered from the Form 1099-R provided by the payer.  This electronically "attaches" the Form 1099-R to your e-filed tax return so that you do not need to provide the IRS with the printed Copy B.

If you are filing by mailing a printed federal tax return, you must attach Copy B that you received from the payer.

If you are e-filing your tax return you do not need to attach the form 1099-R.

If you are going to print and mall your tax return make a copy of the 1099-R and attach it to the federal tax return, Form 1040.
