turbo tax 的答复：

TurboTax Desktop will only handle about 2000 stock transactions. Instead, you can enter summary totals.  If any of your summary totals are greater than $10 million, you will have to use a work around.  You will have to split that summary into more than one transaction.  For instance, if your Short Term Non-Covered transactions total $12,000,000 you will need to split it in to three summaries of $4,000,000 each.

How to enter a summary in lieu of individual transactions

Your brokerage statements should include a summary of your transactions, grouped by sales category, for example, "Box A short-term covered" or "Box D long-term covered". You'll enter the summary info instead of each individual transaction.

1. Open your return (if it's not already open) and search inside TurboTax for the phrase stock sales.
2. Select the Jump to link in the search results.
3. Answer Yes to both Did you sell any investments? and Did you get a 1099-B?
   • If you land on Here's the investment sales info we have so far, select Add More Sales. Then answer Yes to Did you get a 1099-B?
4. When asked how you want to enter your 1099-B, select I'll type it in myself.
5. Select or enter your brokerage on the next screen and continue.
6. On the following screen (Tell us about...) select the second option, I'll enter a summary.
7. On the same screen, you'll now be able to enter the total proceeds (sales) and cost basis, along with the sales category. Refer to your 1099-B for the amounts and category. When finished, select Done.
8. Follow the onscreen instructions to enter additional sales or to view a summary.
