Due to lack of Form 1099 B, and having just Form 8949 , not sure how to to enter same into the TurboTax as it has around 4k transactions. Any help would be appreciated.

Instead of importing each transaction from Binance, enter the category totals from the 8949 from TaxBit.  

You can enter category totals instead of individual transactions.  To do so,

• Click on Search
• In the Search Window type 1099-B
• Click on Jump to 1099-B
• Click Add more sales (if the account you were trying to download is showing, delete it first)
• Click on the box with Stocks, Bonds, Mutual Funds  and click on Enter
• On the Let's import your tax info screen, click on I'll type it myself at the bottom right of the page
• Enter your Broker, and click on Continue
• On the page with "Tell us about your 1099-B sales for this brokerage account" answer the question about employee stock & the number of sales, etc.
• click the button "Enter sales section totals" and click on Continue
• Locate your sales section totals on your 1099-B
• Enter your Investment Sales Section Totals and repeat till you have entered for each category.

After entering all your sales section totals,  Look for "Now we'll help you upload your 1099-B since the IRS requires a copy" and follow the instructions,  or you can mail a paper copy of your 1099-B to the IRS.  If you want to mail, click on "How do I mail my statement".

You can mail the 8949 from TaxBit instead of a 1099-B.

Take a moment to double-check that your statements are complete. For each sale listed, there should be:

•  - A Description
•  - Date Acquired
•  - Date Sold
•  - Sales Price
•  - Cost Basis
•  - Gain or loss for each sale
•  - A category based on how the sale was reported to you and the IRS

 In some uncommon cases, there will be an adjustment code and adjustment amount.

 NOTE: Any sales summaries that include only Box A or Box D sales, and which have no adjustments to gain/loss, do not need to be included on a statement mailed to the IRS.

 Here's how to mail your statements:

 If you are e-filing your tax return, then mail your statements along with Form 8453 to:

Internal Revenue Service

Attn: Shipping and Receiving, 0254

Receipt and Control Branch

Austin, TX 73344-0254

If you are not e-filing, then mail your statements with your entire tax return to your local IRS office.

Thanks David. You are spot on and made life easy.
