Retirement tax questions

@TomYoung @RobertB4444 

Can you help me out? I received a single stock certificate from my ESOP distribution when I left my former employer.  I deposited the stock certificate in my TD Ameritrade account immediately afterwards and sold a number of shares. The remaining unsold shares are still in my TDA account.

 

My situation is like this (numbers for demonstration purposes only. not actual figures):

 

9000 shares issued. Share price at time of issuance = $10.00

Sold 7000 shares at $11/share a few days later.

2000 shares remain in my TDA account. Current market value = $5.00/share

 

1099-R data from former employer:

Box 1: $90,000

Box 2a: $90,000

Box 2b: Total distribution box is checked.

Box 6 NUA: $78,000

 

1099-B from TDA:

Box 1d (Proceeds):  $77,000

Cost basis: BLANK

 

My questions are:

 

1. In Turbo Tax Premier Online, can I simply enter $12,000 for Box 2a of 1099-R (Box 6 NUA - Box 1)?

2. What should I enter as my cost basis for the 7000 shares sold at $11/share? 

 

Thank you for your help.
