Wow...if they told you "each field can take up to 3 minutes to reprocess", then I guess they're aware of the bad coding and there is nothing end-users can do other than to use their fastest computer.
Since they know of the problem, they really should stop the "reprocessing" after each field is entered, or at least make it an option to recalculate the tax return after all W-2 info has been entered.
