So I filed on Feb 1st thinking I had everything I needed and it was accepted the next day... and then I ended up getting 4 more tax documents in the mail days after, the latest one on Friday and now I don't know what to do. and I don't want to go to jail or something for messing up my taxes so badly lol.
What can I do in this situation???
You will not go to jail. You will just learn a lesson the hard way---which is never file your tax return until you have waited and received ALL of your documents. Now you will go through the aggravation of amending your tax return and waiting a long time for the IRS to process your amended return.
You cannot change or add anything on the return that you just e-filed, nor can you stop it. It is too late, just like when you put an envelope in a US mailbox on the corner. The IRS does not allow you to take it back.
If you left out a W-2, a 1099G, or a dependent, or a 1099 etc…DO NOT change your return while it is “pending.” The changes will go nowhere.
Now you have to wait until the IRS either rejects or accepts your return. If your return is rejected, you will be able to go into your account and make the necessary changes to your tax return and re-submit your return.
If the IRS accepts your return, however, then you have to wait longer until it has been fully processed and you have received your refund. THEN you can prepare an amended tax return and e-file or mail it in. You have to be able to work from that return exactly the way it was when it was e-filed originally. You will need to use a form called a 1040X.
Meanwhile, DO NOT go in and start changing anything on your return in the system, or you will make a mess for yourself. Sit tight and wait until you see what the IRS does with the return you just e-filed
The Form 1040X you need will not be available until mid-March.
Here is another option for you:
You can file another return before the due date, but you have to file by paper. After you print out (and sign and date) your return, on the top of Form 1040, write "Superseding Return" so that the IRS knows that you are replacing your originally filed return.
Most likely you still have to file an amended state return unless your state is one of those states that do not have an individual income tax.
Or do as @xmasbaby0 suggested.
