Troubleshooting

I have one Warning about a T3 saying "The sum of capital gains before June 25 in box 52, and capital gains after June 24 in box 53, must equal the total capital gains in box 21. Review and adjust your entries".  I called Turbotax support [phone number removed] yesterday and today...Complete nightmare. Useless automated assistant and unhelpful human help. It seems to me the simple fix is for the software to read BOX 21 and ignore boxes 52 and 53.  How difficult is that to fix?  I tried four times to import data from CRA, but that fails EVERY TIME too.  I am so ANGRY at Intuit for this mess. I want a IMMEDIATE fix and a REFUND of for my purchase of TurboTax Standard.  This is horrible.  Other users say this creates errors in Netfile. I haven't even tried that yet. FIX YOUR SOFTWARE NOW!
