Form 2210 had asked for 4 withholding periods, but it was updated for only 3. The fourth value is locked in and causing errors.

Prior to 2/26, TurboTax Online supported the Q&A questions for Form 2210.  When entering actual withholding, there were four periods shown (although there were some date issues in those periods).  Assuming it would be the same as prior years, I had entered withholding for dates ending 4/15, 6/15, 9/15, and 12/31.  After the update, the form changed to only three periods ending on 7/15, 9/15, and 12/31.  When I reset the numbers, TurboTax complains that the numbers don't add up to the total withholding.  It appears the Line D validation is still adding in the OLD 6/15 value.  The three values in Line D show the NEW 7/15, OLD 6/15, and NEW 9/15.  The lines in Section A show the NEW 7/15, NEW 9/15, and NEW 12/31.  If I play with the numbers so that both Line D and Section A independently add to the correct amount, Turbotax still complains, leading me to believe the OLD 6/15 value is getting added to Line D along with all three new values.  This needs to get fixed ASAP, as TurboTax refuses to e-file when it believes there are issues.  I have already paid my fees, so TurboTax online does not even give me an option to clear data and start over.
