That depends on which version of the software you use. If you can use Deluxe online, the current fees for federal are $39 for federal and $39 for state. If you use "refund processing" to pay those fees, there is an extra fee of $40---you can avoid that fee if you pay before you e-file using a credit or debit card.
If there is something else you forgot to mention--- like self-employment income-- you might have to upgrade to Premium at a higher fee.
If Social Security is your ONLY income, you are not required to file a tax return unless you had tax withheld from your SS, or unless you have a 1095A for marketplace health insurance. If you have other retirement income like money from a 401k, IRA, pension, etc. you have to file if:
You need to file a federal return if half your Social Security plus your other income is
Single or Head of Household $25,000
Married Filing Jointly $32,000
Married Filing Separately $0
If you require a paid edition, and if it's online Deluxe, I believe the current fee is $49 for Federal and $39 for state. Online Premium is currently $99 for Federal and $39 for state. Also be aware that these current fees are discounted. Historically, on March 1 they revert to the undiscounted price, i.e., the price will increase if not paid before then. If it gets close to March 1, and you're not ready to file, you can pay in advance to lock in the discounted fee. We can tell you how.
