I'll help confirm your estimated taxes question, @itaewankim88.
Yes, you're correct. Estimated state tax payments are not part of estimated taxes when you export the info from QuickBooks Self-Employed (QBSE) to TurboTax. It's because the program only covers federal income and self-employment taxes. For more details, check out this article: Send Your Tax Info To TurboTax Online.
To help you get ready for tax filing, we compile a to-do list to make this process easier for you. With this, I'd suggest visiting this website: Annual Taxes Guide. It contains more information about completing the Tax Checklist, creating a file of all your tax documents, and running year-end reports.
I'll be right here to help if you need anything else. Have a great rest of your weekend, @itaewankim88.
