Need to amend 2018 1040 after CP2000 for crypto Coinbase

[ben_g]

Because Coinbase  is only giving users a 1099-K form, and I need to include a form 8949 and 1040, can I just submit an amended 1099-B with the original 1099-K?

Would the step to take be: 
1. Download and fill out https://www.irs.gov/pub/irs-pdf/f1040x.pdf amendment 

2. Fill out the standardized deductions form https://www.irs.gov/pub/irs-pdf/f1040sd.pdf
3. Also fill out an 8949 with trades https://www.irs.gov/pub/irs-pdf/f8949.pdf 
4. Mail all this and the original 1099-k from Coinbase and 1040

On the CP2000 it says I have $142,000 in payment car and third part transactions, and owe $48,000 in taxes. Except this view is changing this year on how the IRS view crypto. They will instead be sending out 1099-B from Coinbase, so does the tax year that needs amending go by what the law was then, or what it is now?

I used turbotax for my 2018 and 2019, so i downloaded the 2018 Turbotax Amend software, but can't find my 2018 tax statements that's accepted by the 2018 Turbotax Amend software. The files 2018 tax return files I can download from Turbotax are in pdf while the software asks for a .tax2018 file. Any assistance to the above questions and this will be greatly appreciated.

Got it, thanks. 

Ok so can I amend my 2018 1040 with a 1040-X and include a form 9849 and 1040-B with the original documents?

Yes, you can enter the investment sale using the Form 1099-B received from the broker in the amend program.  The program will create a Schedule D and a Form 8949 to report the sale on your tax return.

Thanks.

I now have my 8949 alongside my short and long term gains. So where in the 2018 Turbotax software can I enter this?

Do I just attach these complete forms to the original 1099-K and CP2000 and put a cover letter explaining the differences, and fax them into the IRS?
