How do I report TurboTax Software Errors?

I got error message: Form TC-40A: My529 credit should not be more than $200 per qualified beneficiary. But the maximum allowable contribution amount was increased from $4000 to $4080 in 2020, so the credit was also increased to $204.

Here is the link of My529:

My HI State estimated tax payments for 2020 was based on my 2019 tax liability less credits.    My 2019 taxes were imported into the 2020 tax program.   The 2020 turbotax program calculates a  late payment  penalty based on my 2019  tax liability without consideration of the credits.   So it erroneously says that I have HI State late payment penalties.   

I imported data from my broker. Interest and dividend sections are fine. When i try to go into the 'stocks, mutual funds, bonds, other' section turbotax hangs. 

Stimulus checks that were not received. The credit does not appear to be calcuting correctly.  I was suppose to receive a check for $733 and the credit is for $425.  Now here does it ask you for the missing check amount or the year it was based on.

I have found a legitimate calculation error.  It is reported on this set of discussions in the community.  How do we get this fixed in the software?

I am working on my 2020 taxes and have discovered the Qualified Dividends and Capital Gains Tax worksheet does not compute the proper tax for either line 22 nor line 24.  We are married filing jointly.

Line 22 calculates a tax on $301,272 as $60,464 where the proper computation is $68,885.  The formula to be used should be 37,631+.24*(income-$171,050) which for $301,272 computes as $68,885.  The base amount TurboTax used to get the wrong number would be an income of $266,187.50 rather than the actual $301,272.

The same problem is on line 24.  The amount Turbo Tax computed should be on the income amount of $398,702 giving tax of $101,457 instead of the incorrect computation of $89,616 which would be for a income level of $361,702.  What do I do to have this corrected, either my calculations or TurboTax

2020 Form 2210

Keeps returning an error in my entries for FIT paid 1/1-7/15, 7/16-9/15, and 9/16-12/31.

I put one set of entries in "walk-through" by Turbotax, but when I view the actual Form 2210, the values do not match data entry.  I zeroed out all data and started over on this section but same error occurs.

NJ State Return Capital Gains transfers from Federal correctly as seen on initial summary screen.

    This is an addition of the Cap Gains from 1099-DIV and Long Term Capital Gains

NJ Capital Gains Specific Screen lists only the Capital Gains reported on 1099-DIV - if you leave this number, then Turbo Tax replaces the original correct number with only the 1099-DIV.

I had to make note of the summarized number from the initial screen and overwrite.

I had so many issues this year with my taxes by TURBO Tax, where to begin???

There was a W-2 from a prior year which was no longer needed. I deleted it, let me count the times. Several times in the Federal Review, it would come up as something to be fixed because all the fields were blank.

Then there was the 1099-R which was for me not my husband. I corrected it many times, several ways:

Just change the radial button to select me not my husband. Enter a new row for me and delete one for my husband.

NJ State sometimes it was listed as me and sometimes my husband. I don't care anymore that it is currently

incorrect because it shouldn't affect taxes owed.

I started exiting to log changes as soon as I made this changes hoping they would finally take.

I had to delete and start my NJ State Return several times because the incorrect numbers would transfer from Federal for credits for taxes paid from: Prior Year Tax Return, Estimated Payments and amounts paid on W-2, 1099-Rs

The credits would multiply which would make my taxes owed a whopping amount overpaid. I couldn't correct it, I had to delete NJ and start again and again and again.

If Turbo Tax does not fix these problems, I don't see myself as a returning customer.
