IRS rejected - IND-517-01

The IRS rejected my return a couple of times, code IND-517-01. My daughter accidentally indicated on her return that she can't be claimed but she can. She has amended her return through Turbotax via e-file but I'm still getting this error - presumably because the IRS has not yet processed her return.  I owe money this year on my return. Recommendations on the community boards are for me to file via mail.  That of course will take forever.  Is that in fact the best course? Or should I change my return to NOT claim my daughter, e-file and pay my taxes, then file an amendment through e-file to claim my daughter and later get a refund of my overpayment due to now receiving the child tax credit? I've never filed by mail so I'm concerned that might flag an audit of some sort.
