@ssp0 , @SOMENBOGU , while I was not aware of this issue --- I will try this and see why TurboTax misbehaves ( i.e. does not allow e-file while a 3520/3520A is effective), a way around would be to prepare the return as usual, do not select 3520 ( i.e. none 3520 series are being included ), e-file as usual, then come back in, go through the process to prepare the 3520, select file by mail, print out the form 3520 and mail that ONLY by mail -- this is just satisfy the idiosyncrasy of the software ( at present state).
I will try simulate the situation and see why this issue and then call attention of Turbo folks/.
Please accept my apologies for the inconvenient situation.
