JBlazer: No, you shouldn't have to enter all your desktop tax entries just to file an extension. If you're using this site/link: https://turbotax.intuit.com/irs-tax-extensions/ You login with our Intuit account. Then it asks you 2 questions (if you were in the military or lived in Puerto Rico). How you plan to file. Your address. Then it asks these 2 questions:
Estimated 2024 federal total tax liability (form 1040, line 24)
Total 2024 federal taxes paid (Box 2 from your W-2(s), Box 4 from your 1099(s), and quarterly estimated tax payments)
Leave this blank if it doesn't apply to you
It will show if you anticipate owing tax or getting a refund. If owing, it will want a payment/payment plan. If a refund, you will basically not have to enter anything else.
This site may be easier for you but it's only used if you need to make a payment. You select the option EXTENSION and then it allows you to make a one-time payment: https://directpay.irs.gov/directpay/payment?execution=e1s1
