Turbo Tax is a self prepared return. They only guarantee the calculations are right based on your entries. They won't know if you entered something wrong or twice or in the wrong place or left something out. It doesn't check against any outside sources. The IRS has copies of all the W2s and 1099s your employer and banks/brokers, etc. sent in to match against. Turbo Tax only checks the calculations of what you entered. It is your responsibility to check it over before you file.
There have been a lot of mistakes about the Recovery Rebate Credit and Child Tax Credit, lines 28 & 30 on the returns. People are not entering the right amounts they already got for the 3rd Stimulus and Advance Child Credit. Those lines are just if you didn't get the right amounts or qualify for more.
And the IRS is taking a longer time this year to process returns, whether you efiled or mailed it. Like over 6 months.
