The amount on line 45200 T1 General is populated from REFMED - line 21. As it says on the form, line 21 is line 19 minus line 20. If the amount is negative, line 21 will be 0, and will also be 0 at line 45200 of T1 General See screenshot).

Thank you for choosing TurboTax.

If line 19 has a $amount and line 20 is zero then line 21 needs to have a dollar amount to carry forward to line 45200.  The program is not doing the calculation

Is it possible for you to send us a screenshot of this section from your form, please?

I have attempted several ways to upload a photo and it continually tells me the file is too large.  Open the REFMED worksheet which populates from entered medical expenses.  I am currently working on 2 separate tax returns.  One file has the calculated $amount on line 19 and zero on Line 20 so should do the math calculation to be 19 minus 20 and populate Line 21 to carry over to T1 General line 45200.  On the other tax form there is a $amount on Line 19  greater than the $amount on 20 and still does not do the math calculation to carry forward to line 45200.

It looks like an update has fixed this. Please make sure your copy of TurboTax is updated and check again.

I have requested a Turbo Tax update and receive the message that I am up to date?  I have not received any new updates for quite some time?

You may need to do a manual update. 

What is a manual update?

Thanks for showing me a photo of a REFMED worksheet in your test environment that completes the calculation, however, there have been no new updates to Turbo Tax recently.  When can we expect the fix for this problem?
