I'm not going to wait for ProSeries to release the final version of Form 7203. I have some pretty straight forward S Corp returns and the client want to get their refund going (certainly understandable). 

Any reason why I can't just prepare the Form 7203 on my own and attach it? Doesn't say anywhere in the Form 7203 instructions that it must be embedded with the 1040 and not allowed as a separate attachment.
