Amend or Late file - Need advice

Hi,

 

I am awaiting SSN for my 8 year old daughter sometime next week. However, due to Federal holiday on Monday, I am now skeptical if I will receive the mail by Friday. I have already paid my tax due during April when I requested for extension.  Since my daughter was having ITIN last year, she didn't qualify for the federal tax stimulus. I was hoping that when I file the returns now after we receive her SSN, I can possibly claim the stimulus.

 

Now that I am anticipating a delay in SSN, I have only the following options.

 

1. File taxes by Oct 15 and leave the hope of claiming any unpaid stimulus

2. File taxes by Oct 15 and later file an amendment once we receive my child's SSN. I never amended my tax returns so it's a grey area for me. Is it something I can do self serve on turbo tax? And will I get an opportunity to include my child's SSN during amendment process?

3. Wait for the SSN and then file taxes even if it crosses the Oct 15 deadline. What are the repercussions? Is it going to be any penalty or will it be unlawful as well? I don't want to mess with IRS. Btw, I have already paid more than what I am due just to be sure that I don't incur any penalty.

 

Please suggest which of the options is wise given my situation.
