E-filed it was rejected for an already claimed dependent. Printed tax forms but I now wish to correct and efile. Turbo tax does not allow me to correct because I printed

you would have to remove the dependent that was already claimed to e-file.

if you go this route you have to go to the point where you select to e-file rather than print

May be remove the old one and try again can solve this issue. Just google or read light novels if provided any book
