Filing 1099-r with Form 1040-SR

I have the CD/download Premier Edition of Turbotax.  I've completed the return and want to e-file it. BUT I must submit the 1099-R I received from my pension plan for the RMD I received with the return.  This 1099-R shows the tax withholding from the distribution and therefore has to be filed with the return.   I was at the final turbotax screen to e-file with the warning that you can't make changes if you proceed.  I stopped because I don't know if I press this button how a copy of this  1099-R will be filed.  How does this work if I e-file?  I know I can print out the return, attach the 1099-R and do a mail filing.  But I would prefer to e-file if that is possible.  How would I handle this?
