To everyone who would like to know what changed after filing (or completing your return and are waiting to file), it is not that hard to see what changed. Print out the return(s) with all worksheets (actually save as a pdf, you never want to print out the "records" version), then open the program shortly before the deadline, let it update, and don't change anything. Print out another copy with all worksheets and compare the two versions.
While this could be tedious, start by checking a few key amounts--taxable income, AGI, Tax calculations, bottom line numbers on the forms that get filed, etc., then scan the list of bookmarks to see if there are any new pages. This may narrow the changes down and indicate whether something critical has changed. Most updates at this point are to fix programming bugs that may only affect a few people. If main forms are all the same you don't have anything to worry about. If there are differences, you have the worksheets to find the changes that affect you. If necessary, then you can file an amended return and mail it in.
