I've started to file my income tax with the HR Block free file service, but I'm getting hit with a 30 dollar upgrade prompt when I go to put in my 1099s. I have one capital gains 1099-MISC, one savings account 1099-INT, and one 1099-MISC from working as an Amazon delivery contractor. Is there a different free file provider that doesn't charge for 1099 entry? I'd prefer not to guess and test a bunch. And if not, is it too late to mail a 1040 as of 4/13/18? Thanks.
I don’t know for sure whether or not there are any free tax software apps that handle your situation, but when you did the job that got you the 1099-MISC you were technically self-employed. This complicates your return and is an advanced feature that is not generally available in the free versions of tax software.
To answer your second question, the tax due date this year is Tuesday, April 17, 2018. Your mailed return needs to be postmarked by that date. Post Offices used to stay open on tax day until midnight to accommodate late filers. I don’t think they all do that anymore, but some are still open late that day, and as long as you get your tax return to your local post office before it closes that day, you should be fine.
